Yankton County Highway Funding
April 14, 2016. The James River Water Development District awarded $78,000 to the Yankton County Highway Department to install a box culvert with riprap located in Walshtown Township. The structure is currently posted at 3 tons gross and is in very poor condition. The original structure will be replaced with a concrete box culvert sized for a 10 year runoff event and raise the elevation of the road 2 feet above the existing structures.
